SMOKING-PIPE.

Specification of Letters Patent.

Patented May 2o, 1919.

Application led April 16, 1918. Serial No. 228,894.

To all whom t may concern.'

Be it known that I, EDWIN B. GRACE, a citizen of the United States,residing at vMemphis, in the county of Shelby and State This inventionrelates to new and usefulv improvements in smoking pipes and the primaryobject of the invention is to provide a smoking pipe provided with meansfor draining the saliva therefrom to prevent the pipe from becomingfouled and permitting the same to be always kept clean and sanltary.

Another object of the invention is to provide a device of this characterwhich is easily and simply constructed, inexpensive to manufacture, andone which will be very efficient in operation.

With these and numerous other objects in View, my invention consists ofthe novel features of construction, combination and arrangement of partswhich will be herein referred to and more particularly pointed out inthe specification and claim.

In the accompanying drawings:

Figure 1 is a vertical longitudinal section through the bowl portion ofa pipe,

Fig. 2 is a similar detail view of the valve arrangement, showing thevalve in a different",i position from that illustrated in Fig. 1, an

Fig. 3 is a detail perspective view of the closure secured to the bottomof the pipe.

In describing my invention, I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views.

, The numeral 1 designates the bowl portion of the conventional type ofsmoking pipe provided with the usual tobacco receiving c amber 2 thereinand said bowl portion is rovided with an upwardly projecting nec 3 thathas connected with the outer end thereof the conventional type of stem4. Positioned in the neck portion of the pipe is a saliva well 5 andcommunicating with the upper portion of the well is a smoke passage 6that extends from said well to the bottom of the bowl 2 in which thetobacco is placed.

The lower edge of the well 5 communicates with a vertical passagethrough the neck portion 3 adjacent the bowl 1 and said passage haspositioned therein a rotatable valve plug 7 having its upper endprojecting above the edge of the portion through which it is positionedand roughened as shown at 8 so as to permit a ready rotation thereof.The lower end of the plug 7 extends through the bottom of the pipe andits lower edge lies iush with the bottom thereof.

Posltioned through the bottom `of the plug 7 is an angular outletpassage 9 which has one end through the lower end of the plug while theother portion thereof extends at right angles and is adapted tocommunicate at times with the outlet of the saliva well 5. The plug 7 islikewise provided with an angular diametrically extending passage 10therethrough adjacent its upper end, sald passage being adapted at timesto aline with the passage 6 through which the plug is positioned.

In operation when the plug is arranged as is clearly shown in Fi 1 ofthe drawings, the pipe may be smoked 1n the usual manner, and saliva andnicotine that collect therein will be caught in the well 5 and will beprevented from passing through the smoke passage 6 into the bowl of thepipe. When it is desired to drain the saliva, well 5 the plug 7 1srotated by grasping the projecting end 8 thereof and rotatlng the same aquarterturn whereby the passage 10 is disalined in the smoke passage andthe upper portion of the outlet passage 9 is brought into communicationwith the outlet of the saliva well 5. This permits the saliva to drainthrough this outlet passage from the pipe so that the pipe may be alwayskept clean and sanitary. This drainage is facilitated if user blowsthrough the stem.

The pipe is provided with an additional closure for the outlet passage 9which comprises a flat spring metal strip 11 that has one end connectedwith the bottom of the pipe by a screw 12 or the like, and upon theopposite end 13 thereof, is positioned a closure plug 14 on the innerside thereof that is adapted to be positioned overthe outlet passage 9so as to absolutely prevent any leakage of the saliva from the well 5.This keeps the drain always clean, and prevents any leakage of nicotineor saliva, so 'as the pipe would be likely to soil the users hands orclothes.

From the foregoing description taken in connection with the accompanyingdrawings, it is thought that a clear and comprehensive understanding ofthe construction, operation and advantages of my invention may be had,and while I have shown and described the device as embodying a specicstructure, I desire that it be understood that such changes may be madein said structure as do not depart from the spirit and scope of theinvention as claimed.

Having fully described my invention, what I claim is new, and desire tosecure by Letters Patent is:

A smoking pipe having a saliva well formed in the neck portion thereofand a tapered vertical bore in said neck portion communicating with theWell and the bowl of the pipe, a tapered valve rotatably mounted insaid. bore formed with a Way adapted to communicate, at times, with saidwell and opening outwardly adjacent the lower side of said neck portion,said valve having an obliquely disposed way therethrough forestablishing communication between the stem and bowl portions of thepipe bowl and the upper portion of the rotatable valve extending from adistance above the upper side of the neck portion ofthe pipe, and aspring arm carrying a plug on the free end thereof engageable in theouter end of the way formed in the valve communicating with the salivaWell. A

In testimony whereof, I aiix my signature hereto.

EDWIN B. GRACE.
